Our Roots

We opened Trinity River Garden Center way back in 2010 to serve small gardens in our Willow Creek community. We soon realized that we could help out independent farmers that have been relying on outdated information or agricultural folklore.

Since 2013, Humboldt Ag Supply has been offering sustainable fertilizers to small farms throughout Northern California.

We’re taking a precise, data-driven approach to soil fertility management. We’re promoting science on the farm and helping the modern farmer grow — moving away from potting media replacement toward informed nutrient application. And with the experience and expertise of our team of ag industry veterans, we’re making it easier than ever.
